Hello, I've not purchased the plugin yet but have a couple questions for you:

• What are you using for your oauth helper... anything? hybridauth?
• can you easily change the requested permissions (like I need offline access to gmail from google for example)?

• I'm using HybridAuth for Twitter/FB, google/apiclient for Google.
• Can't easily change permissions. I'm not sure of a generic, easy way to allow this. I may just add an event you can hook into for Google if it'll help.
